Application May 1, 1939, Serial No. 27l, 156 4 Claims. (01. 292-45) Thisinvention appertains to new and useful improvements in door fastenersespecially adapted for automobiles and other vehicles, and the principalobject of the invention is to provide a door latch which iseasilycontrolled either in the opening or closing of the door and which willbe self-tightening, thus eliminating door rattling.

Another important object of the invention is to provide a door fastenerof the character stated which will be of simple construction,substantially fool-proof in operation and not susceptible to the readydevelopment of defects.

Inthe drawings:

Figure 1 represents a sectional view taken substantially on a line II ofFigure 2.

Figure 2 is a fragmentary horizontal sectional view.

Figure 3 is a fragmentary vertical sectional view through the latch ineffected position.

Figure 4 is a sectional view taken substantially on a line 44 of Figure3.

Figure 5 is a perspective view of the bolt wedge assembly.

Figure 6 is a top plan view of the latch assembly in closed position.

Figure '7 is a sectional view taken substantially on a line 'I-! ofFigure 6.

Figure 8 is a side elevational view of the cam.

Figure 9 is a perspective view of the spring for the rollers.

Referring to the drawings, wherein like numerals designate like parts,it can be seen in Figures 1 and 2', that numeral 5 represents the bodyof the vehicle which at the jamb edge of the door opening is providedwith the plate 6 suitably secured to the body 5 and this plate 6 -hassuitably secured thereto as at l'| a pair ofarms 8-9, each carrying aroller Ill. The

upper edge of the arm 8 and. the lower edge of the arm 3 is notched toreceive the inwardly curved end portions II of the leaf spring I2, a lugl3 on the plate serving to prevent displacement of this spring 12. A lugI4 projects outwardly from the plate 6 to support the arm 8 and tends tokeep the rollers l0 properly aligned with respect to the wedge bolt l5,this bolt l5 being carried by the jamb side of the case I6, this casebeing mounted on the edge of the door I! opposed to the plate 6.

The case I6 has the outwardly extending lugs I8 through which the pin I9is slidably disposed, this pin extending into the recess 20 of the wedgebolt I5 and being threadedly engaged as at 2| in the inner end wall ofthe said recess 28; C'onvoluted on the pin l9 and being interposedbetween thesaid innerwall of the recess 28 and the lug I9 is thecompression spring 22.

The wedge bolt I5 is of wedge shape and has the laterally disposed web23 which is slidably disposed through the slot 24 in the case IS. Theinner end of the web 23 which has the guide flange 25 for wipingengagement against the inner side of the case l6 supports the roller 26at its inner end. 10

A shaft 21 is journalled through one side wall 28 of the case I6 and hasits other end reduced and journalled as at 29 in the opposite side wall30 of the case I6. The outer end of the shaft 21 is provided with theoperating handle 15 32. The shaft 21 at a point in the case I6 carriesthe cam wheel 33 for riding engagement with the roller 26. A catch andspring has one end anchored to the cam side of the case l6 as at 34 andits other end attached to the cam 20 wheel 33. I

As can be seen in Figure 6 and also in Figure 1, a pair of bosses,namely an upper boss 34 and a lower boss 35 are provided on the cam wall36 of the case I6 and between these the 25 wedge bolt I5 normallyprotrudes. The bosses 34 and 35 have inboard bevels 31 to facilitatepassing between the bosses 34 and 35 of the rollers l8 and outboardbevels 38 against which surfaces the rollers are held by the wedging 30effect of the wedge bolt l5.

It can now be seen that when the door I! is pushed to a closed positionthe rollers II] will ride inwardly and push the wedge bolt 15 outwardlyuntil the rollers Ill start riding on the 5 bevelled surfaces 38whereupon the effect of the spring 22 will be to spread the rollersapart and thus prevent return of the rollers.

Torelease the wedge bolt I5, the handle 32 is rotated and this operatesthe cam 33 so that 40 the roller 26 is moved outwardly, thus retractingthe wedge bolt l5 so that the spring I2 can contract the rollers III,thus freeing the door so that it can be readily swung to an openposition without any further effort. 45

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the inven- 50 tion as claimed hereinafter.

Having described the what is invention,

- claimed as new is:

ably mounted deflecting member for deflecting and holding the rolleragainst the keeper, said deflecting member being provided with alaterally disposed rider, a cam, rotatably mounted, manual means foroperating the cam, said rider being engaged with the rotary cam, saidcam being operative by said manual means to actuate the rider and shiftthe deflecting member from roller engaged position.

2. A closure fastener comprising .a swingably mounted roller, a bevelledkeeper, and a yieldably mounted deflecting member for deflecting andholding the roller against the keeper, said derollers, a pair of pivotalarms carrying the said fleeting member being provided with a laterallydisposed rider, a cam rotatably mounted, man-.

ual means for operating the cam, said rider being engaged with therotary cam, said cam being operative by said manual means to actuate therider and shift the deflecting member \fromv 3. A closure fastenercomprising a swingably mounted roll-er, a bevelled keeper, and ayieldably mounted deflecting member for deflecting and holding theroller against the keeper, said deflecting member being provided with alaterally disposed rider, a cam rotatably mounted,

manual means for operating the cam, said rider being engaged with therotary cam, said cam being operative by said manual means to actuate therider, and shift the deflectingmember from roller engaged position andspring return means for the rotary cam.

4. A closure fastener comprising a pair of rollers, a pair of beveledclosure carried bosses each having a beveled surface, a wedge memberadapted to deflect the rollers to engage the beveled surfaces of thebosses, means for retracting the wedge member to release the arms andthe rollers from the beveled bosses, and a spring member having its endportions disposed inwardly and adapted to engage the arms to force thesame toward each other.
